142-695: The Irrawaddy River ( Burmese : ဧရာဝတီမြစ် , pronounced [ʔèjàwədì mjɪʔ] , official romanisation: Ayeyarwady ) is the largest river in Myanmar . Originating from the confluence of the N'mai and Mali rivers, it flows from north to south before emptying through the Irrawaddy Delta in the Ayeyarwady Region into the Andaman Sea. Its drainage basin of about 404,000 square kilometres (156,000 sq mi) covers 61% of

284-565: A pitch-register language like Shanghainese . There are four contrastive tones in Burmese. In the following table, the tones are shown marked on the vowel /a/ as an example. For example, the following words are distinguished from each other only on the basis of tone: In syllables ending with /ɰ̃/ , the checked tone is excluded: In spoken Burmese, some linguists classify two real tones (there are four nominal tones transcribed in written Burmese), "high" (applied to words that terminate with

426-645: A subject–object–verb word order. It is a member of the Lolo-Burmese grouping of the Sino-Tibetan language family . The Burmese alphabet is ultimately descended from a Brahmic script , either the Kadamba or Pallava alphabets. Burmese belongs to the Southern Burmish branch of the Sino-Tibetan languages , of which Burmese is the most widely spoken of the non- Sinitic languages. Burmese

568-614: A concentrated belt that stretches east–west except in East China where it is tilted east-northeast over Korea and Japan. The seasonal rain is known as Meiyu in China, Jangma in Korea, and Bai-u in Japan, with the latter two resembling frontal rain. The onset of the summer monsoon is marked by a period of premonsoonal rain over South China and Taiwan in early May. From May through August,

710-473: A considerable amount of passenger and goods traffic moves by river. As the Irrawaddy Delta is one of the world's major rice-growing areas, one of the most important goods transported is rice. Teak logs – Myanmar is one of the world's top exporters – are floated down the river as large rafts. Before it is transported, teak has to be seasoned, because otherwise it won't float. This happens by girdling ,

852-596: A distal depocenter, up to 60 m in thickness, has been deposited seaward in the Gulf of Martaban, extending to ~130 m water depth into the Martaban Depression. Further, 2) There is no evidence showing that modern sediment has accumulated or is transported into the Martaban Canyon; 3) There is a mud drape/blanket wrapping around the narrow western Myanmar Shelf in the eastern Bay of Bengal. The thickness of

994-622: A few sub-systems, such as the Indian Subcontinental Monsoon which affects the Indian subcontinent and surrounding regions including Nepal, and the East Asian Monsoon which affects southern China, Taiwan , Korea and parts of Japan. The southwestern summer monsoons occur from June through September. The Thar Desert and adjoining areas of the northern and central Indian subcontinent heat up considerably during

1136-554: A large-scale sea breeze caused by higher temperature over land than in the ocean. This is no longer considered as the cause and the monsoon is now considered a planetary-scale phenomenon involving the annual migration of the Intertropical Convergence Zone between its northern and southern limits. The limits of the ITCZ vary according to the land–sea heating contrast and it is thought that the northern extent of

1278-550: A lesser extent, Burmese has also imported words from Sanskrit (religion), Hindi (food, administration, and shipping), and Chinese (games and food). Burmese has also imported a handful of words from other European languages such as Portuguese . Here is a sample of loan words found in Burmese: Since the end of British rule, the Burmese government has attempted to limit usage of Western loans (especially from English) by coining new words ( neologisms ). For instance, for

1420-547: A low pressure system known as a monsoon trough develops over South-East Asia and Australasia and winds are directed toward Australia. In the Philippines, northeast monsoon is called Amihan . The East Asian monsoon affects large parts of Indochina , the Philippines , China, Taiwan , Korea, Japan, and Siberia . It is characterised by a warm, rainy summer monsoon and a cold, dry winter monsoon. The rain occurs in

1562-413: A lower temperature than the land, and the air above it retains a higher pressure. This difference in pressure causes sea breezes to blow from the ocean to the land, bringing moist air inland. This moist air rises to a higher altitude over land and then it flows back toward the ocean (thus completing the cycle). However, when the air rises, and while it is still over the land, the air cools . This decreases

1704-674: A monk]", Lower Burmese speakers use [sʰʊ́ɰ̃] instead of [sʰwáɰ̃] , which is the pronunciation used in Upper Burma. The standard dialect is represented by the Yangon dialect because of the modern city's media influence and economic clout. In the past, the Mandalay dialect represented standard Burmese. The most noticeable feature of the Mandalay dialect is its use of the first person pronoun ကျွန်တော် , kya.nau [tɕənɔ̀] by both men and women, whereas in Yangon,

1846-668: A narrow valley between forest-covered mountain ranges—the ridge of the Arakan Mountains to the west and that of the Pegu Yoma Mountains to the east. The delta of the Irrawaddy begins about 93 kilometres (58 mi) above Hinthada (Henzada) and about 290 kilometres (180 mi) from its curved base, which faces the Andaman Sea. The westernmost distributary of the delta is the Pathein (Bassein) River, while

1988-661: A period of global cooling and sea level fall. The EASM was weaker during cold intervals of glacial periods such as the Last Glacial Maximum (LGM) and stronger during interglacials and warm intervals of glacial periods. Another EAWM intensification event occurred 2.6 million years ago, followed by yet another one around 1.0 million years ago. During Dansgaard–Oeschger events , the EASM grew in strength, but it has been suggested to have decreased in strength during Heinrich events . The EASM expanded its influence deeper into

2130-416: A practice where a deep circular cut through bark and sapwood is made into the heartwood. Other major goods that are transported from the nation's heartlands to Yangon for export are other foodstuffs, petroleum, cotton, and local commodities. Commercial transportation on the Irrawaddy is maintained for about 1,300 kilometres (810 mi): from Hinthada to Bhamo (1,080 kilometres (670 mi)) throughout

2272-535: A seasonal reversing wind accompanied by corresponding changes in precipitation but is now used to describe seasonal changes in atmospheric circulation and precipitation associated with annual latitudinal oscillation of the Intertropical Convergence Zone (ITCZ) between its limits to the north and south of the equator. Usually, the term monsoon is used to refer to the rainy phase of a seasonally changing pattern, although technically there

2414-466: A stop or check, high-rising pitch) and "ordinary" (unchecked and non-glottal words, with falling or lower pitch), with those tones encompassing a variety of pitches. The "ordinary" tone consists of a range of pitches. Linguist L. F. Taylor concluded that "conversational rhythm and euphonic intonation possess importance" not found in related tonal languages and that "its tonal system is now in an advanced state of decay." The syllable structure of Burmese

2556-411: A strong tendency to diverge, subside and cause drought. Similar rainfall is caused when moist ocean air is lifted upwards by mountains, surface heating, convergence at the surface, divergence aloft, or from storm-produced outflows at the surface. However the lifting occurs, the air cools due to expansion in lower pressure, and this produces condensation . The monsoon of western Sub-Saharan Africa

2698-571: Is mutual intelligibility among Burmese dialects, as they share a common set of tones, consonant clusters, and written script. However, several Burmese dialects differ substantially from standard Burmese with respect to vocabulary, lexical particles, and rhymes. Spoken Burmese is remarkably uniform among Burmese speakers, particularly those living in the Irrawaddy valley, all of whom use variants of Standard Burmese. The standard dialect of Burmese (the Mandalay - Yangon dialect continuum ) comes from

2840-400: Is C(G)V((V)C), which is to say the onset consists of a consonant optionally followed by a glide , and the rime consists of a monophthong alone, a monophthong with a consonant, or a diphthong with a consonant. The only consonants that can stand in the coda are /ʔ/ and /ɰ̃/ . Some representative words are: Monsoon A monsoon ( / m ɒ n ˈ s uː n / ) is traditionally

2982-612: Is a separate river, tributary to the Yangon . After Rudyard Kipling 's poem, the river is sometimes referred to as ' The Road to Mandalay '. The Irrawaddy River bisects Myanmar from north to south and empties through the nine-armed Irrawaddy Delta into the Indian Ocean. The Irrawaddy River arises by the confluence of the N'mai (Nam Gio) and Mali Rivers in Kachin State . Both the N'mai and Mali Rivers find their sources in

3124-706: Is also a dry phase. The term is also sometimes used to describe locally heavy but short-term rains. The major monsoon systems of the world consist of the West African , Asian– Australian , the North American , and South American monsoons. The term was first used in English in British India and neighboring countries to refer to the big seasonal winds blowing from the Bay of Bengal and Arabian Sea in

3266-630: Is derived from Pali . Irāvatī or Airāvatī ( Erāvatī in Pali) is the name of the elephant mount of Sakka and Indra in Hinduism. Saka is an important deva in Buddhism and elephants were often a symbol for water and were used as the name for several other rivers, such as the Achiravati . It can also be based on Iravati , who birthed the mythological elephant. The Irrawaddy gives its name to

3408-666: Is directly of "cyclonic" (i.e., monsoon-driven) origin (as opposed to " local convection "). The effects also extend westwards to the Mediterranean, where however the impact of the monsoon is to induce drought via the Rodwell-Hoskins mechanism . Around September, with the sun retreating south, the northern landmass of the Indian subcontinent begins to cool off rapidly, and air pressure begins to build over northern India. The Indian Ocean and its surrounding atmosphere still hold their heat, causing cold wind to sweep down from

3550-597: Is involved, Kansai Electric Power Company . Due to its location and size, construction of the Myitsone Dam has raised significant ecological and sociological concerns. According to the Irrawaddy Myitsone Dam Multipurpose Water Utilizing Project study, the maximum water level of the reservoir will be 290 metres. This makes for a flood zone of 766 km, compromising 47 villages. Other consequences of

3692-610: Is known to many as the Summer , Southwest , Mexican or Arizona monsoon. It is also sometimes called the Desert monsoon as a large part of the affected area are the Mojave and Sonoran deserts . However, it is controversial whether the North and South American weather patterns with incomplete wind reversal should be counted as true monsoons. The Asian monsoons may be classified into

3834-463: Is made up of fanlike marshes with oxbow lakes , islands, and meandering streams . Birds of the delta are both winter visitors and passage migrants including great cormorant ( Phalacrocorax carbo ), a wide variety of Anatidae , Eurasian coot ( Fulica atra ), about thirty species of migratory shorebirds , the whiskered tern ( Chlidonias hybrida ), the Caspian tern ( Hydroprogne caspia ), and

3976-460: Is no longer under construction at the convergence of these rivers. The town of Bhamo , about 240 kilometres (150 mi) south of the Mali and N'mai river confluence, is the northernmost city reachable by boat all year round although during the monsoons most of the river cannot be used by boats. The city of Myitkyina lies 50 kilometres (31 mi) south of the confluence and can be reached during

4118-442: Is pronounced [mõ̀ũndã́ĩ] . The vowels of Burmese are: The monophthongs /e/ , /o/ , /ə/ , /ɛ/ and /ɔ/ occur only in open syllables (those without a syllable coda ); the diphthongs /ei/ , /ou/ , /ai/ and /au/ occur only in closed syllables (those with a syllable coda). /ə/ only occurs in a minor syllable , and is the only vowel that is permitted in a minor syllable (see below). The close vowels /i/ and /u/ and

4260-453: Is the most important for plant life, is atmospheric humidity . This is always high, except in the winter in certain localities. Humidity usually does not fall below 75% and is 90% or more for long periods during summer. Another feature is the prevalent southerly summer winds which erode the soil of the basin. The natural habitats of this central zone have been much altered for farming and there are few protected areas. The predominant trees of

4402-523: Is the result of the seasonal shifts of the Intertropical Convergence Zone and the great seasonal temperature and humidity differences between the Sahara and the equatorial Atlantic Ocean. The ITCZ migrates northward from the equatorial Atlantic in February, reaches western Africa on or near June 22, then moves back to the south by October.

4544-584: Is the value of the four native final nasals: ⟨မ်⟩ /m/ , ⟨န်⟩ /n/ , ⟨ဉ်⟩ /ɲ/ , ⟨င်⟩ /ŋ/ , as well as the retroflex ⟨ဏ⟩ /ɳ/ (used in Pali loans) and nasalisation mark anusvara demonstrated here above ka (က → ကံ) which most often stands in for a homorganic nasal word medially as in တံခါး tankhá 'door', and တံတား tantá 'bridge', or else replaces final -m ⟨မ်⟩ in both Pali and native vocabulary, especially after

4686-638: Is the word "moon", which can be လ la̰ (native Tibeto-Burman), စန္ဒာ/စန်း [sàndà]/[sã́] (derivatives of Pali canda 'moon'), or သော်တာ [t̪ɔ̀ dà] (Sanskrit). The consonants of Burmese are as follows: According to Jenny & San San Hnin Tun (2016 :15), contrary to their use of symbols θ and ð, consonants of သ are dental stops ( /t̪, d̪/ ), rather than fricatives ( /θ, ð/ ) or affricates. These phonemes, alongside /sʰ/ , are prone to merger with /t, d, s/ . An alveolar /ɹ/ can occur as an alternate of /j/ in some loanwords. The final nasal /ɰ̃/

4828-491: The [ ɹ ] sound, which has become [ j ] in standard Burmese. Moreover, Arakanese features a variety of vowel differences, including the merger of the ဧ [e] and ဣ [i] vowels. Hence, a word like "blood" သွေး is pronounced [θw é ] in standard Burmese and [θw í ] in Arakanese. The Burmese language's early forms include Old Burmese and Middle Burmese . Old Burmese dates from

4970-588: The /l/ medial, which is otherwise only found in Old Burmese inscriptions. They also often reduce the intensity of the glottal stop . Beik has 250,000 speakers while Tavoyan has 400,000. The grammatical constructs of Burmese dialects in Southern Myanmar show greater Mon influence than Standard Burmese. The most pronounced feature of the Arakanese language of Rakhine State is its retention of

5112-637: The Arabian Sea and that of the wind-blown dust in the Loess Plateau of China, many geologists believe the monsoon first became strong around 8 million years ago. More recently, studies of plant fossils in China and new long-duration sediment records from the South China Sea led to a timing of the monsoon beginning 15–20 million years ago and linked to early Tibetan uplift. Testing of this hypothesis awaits deep ocean sampling by

5254-527: The Burmese alphabet began employing cursive-style circular letters typically used in palm-leaf manuscripts , as opposed to the traditional square block-form letters used in earlier periods. The orthographic conventions used in written Burmese today can largely be traced back to Middle Burmese. Modern Burmese emerged in the mid-18th century. By this time, male literacy in Burma stood at nearly 50%, which enabled

5396-618: The English language in the colonial educational system, especially in higher education. In the 1930s, the Burmese language saw a linguistic revival, precipitated by the establishment of an independent University of Rangoon in 1920 and the inception of a Burmese language major at the university by Pe Maung Tin , modeled on Anglo Saxon language studies at the University of Oxford. Student protests in December of that year, triggered by

5538-756: The Hadley circulation during boreal winter. It is associated with the development of the Siberian High and the movement of the heating maxima from the Northern Hemisphere to the Southern Hemisphere. North-easterly winds flow down Southeast Asia, are turned north-westerly/westerly by Borneo topography towards Australia. This forms a cyclonic circulation vortex over Borneo, which together with descending cold surges of winter air from higher latitudes, cause significant weather phenomena in

5680-575: The Himalayas and Indo-Gangetic Plain towards the vast spans of the Indian Ocean south of the Deccan peninsula. This is known as the Northeast Monsoon or Retreating Monsoon. While travelling towards the Indian Ocean, the cold dry wind picks up some moisture from the Bay of Bengal and pours it over peninsular India and parts of Sri Lanka . Cities like Chennai , which get less rain from

5822-557: The Indonesian Throughflow generally warms the Indian Ocean. Thus these five intervals could probably be those of considerable lowering of SST in the Indian Ocean and would have influenced Indian monsoon intensity. During the weak LC, there is the possibility of reduced intensity of the Indian winter monsoon and strong summer monsoon, because of change in the Indian Ocean dipole due to reduction in net heat input to

5964-627: The Integrated Ocean Drilling Program . The monsoon has varied significantly in strength since this time, largely linked to global climate change , especially the cycle of the Pleistocene ice ages. A study of Asian monsoonal climate cycles from 123,200 to 121,210 years BP, during the Eemian interglacial, suggests that they had an average duration of around 64 years, with the minimum duration being around 50 years and

6106-723: The Mon people , who until recently formed the majority in Lower Burma . Most Mon loanwords are so well assimilated that they are not distinguished as loanwords, as Burmese and Mon were used interchangeably for several centuries in pre-colonial Burma. Mon loans are often related to flora, fauna, administration, textiles, foods, boats, crafts, architecture, and music. As a natural consequence of British rule in Burma , English has been another major source of vocabulary, especially with regard to technology, measurements, and modern institutions. English loanwords tend to take one of three forms: To

Burmese is a diglossic language with two distinguishable registers (or diglossic varieties ): The literary form of Burmese retains archaic and conservative grammatical structures and modifiers (including affixes and pronouns) no longer used in the colloquial form. Literary Burmese, which has not changed significantly since

6390-614: The Pyu language . These indirect borrowings can be traced back to orthographic idiosyncrasies in these loanwords, such as the Burmese word "to worship", which is spelt ပူဇော် ( pūjo ) instead of ပူဇာ ( pūjā ), as would be expected by the original Pali orthography. The transition to Middle Burmese occurred in the 16th century. The transition to Middle Burmese included phonological changes (e.g. mergers of sound pairs that were distinct in Old Burmese) as well as accompanying changes in

6532-574: The Sierra Madre Occidental as well as Arizona , New Mexico , Nevada , Utah , Colorado , West Texas and California . It pushes as far west as the Peninsular Ranges and Transverse Ranges of Southern California, but rarely reaches the coastal strip (a wall of desert thunderstorms only a half-hour's drive away is a common summer sight from the sunny skies along the coast during the monsoon). The North American monsoon

6674-559: The Sittaung River plain to the east of the delta was described in November 1877 as covering 300 square kilometres (100 sq mi) and containing millions of birds. Immense colonies still bred in the area in 1910, but the birds had disappeared completely by 1939. Small numbers were regularly reported in the delta in the 1940s, but no breeding sites were located. As of 2010, no pelicans have been recorded, and it may well be that

6816-408: The [1] shows a 38% decrease in discharge compared to where the river enters the delta. it also silted up around 278 tons of sand every year. Variation between high and low water levels is also great. At Mandalay and Prome , a range of 9.66 to 11.37 metres (31.7–37.3 ft) has been measured between low-water level and flood level respectively. Because of the monsoonal character of the rain,

6958-481: The brown-headed gull ( Larus brunnicephalus ), which is very common. One of the most numerous wintering shorebird is the lesser sand plover ( Charadrius mongolus ), which occurs in flocks of many thousands along the outer coast of the delta. The wood sandpiper ( Tringa glareola ) and red junglefowl ( Gallus gallus ) are also abundant. In the late 19th century, the spot-billed pelican ( Pelecanus philippensis ) nested in huge numbers in south Myanmar. One colony on

The semiarid Sahel and Sudan depend upon this pattern for most of their precipitation. The North American monsoon ( NAM ) occurs from late June or early July into September, originating over Mexico and spreading into the southwest United States by mid-July. It affects Mexico along

7242-618: The return of the westerlies ) is the result of a resurgence of westerly winds from the Atlantic, where they become loaded with wind and rain. These westerly winds are a common phenomenon during the European winter, but they ease as spring approaches in late March and through April and May. The winds pick up again in June, which is why this phenomenon is also referred to as "the return of the westerlies". The rain usually arrives in two waves, at

Among the most well-known species in the river is the Irrawaddy dolphin ( Orcaella brevirostris ), a euryhaline species of oceanic dolphin with a high and rounded forehead, lacking a beak. It is found in discontinuous sub-populations near sea coasts and in estuaries and rivers in parts of the Bay of Bengal and South-East Asia. Along

Word order , grammatical structure, and vocabulary have remained markedly stable well into Modern Burmese, with the exception of lexical content (e.g., function words ). The earliest attested form of

7668-457: The 13th century, is the register of Burmese taught in schools. In most cases, the corresponding affixes in the literary and spoken forms are totally unrelated to each other. Examples of this phenomenon include the following lexical terms: Historically the literary register was preferred for written Burmese on the grounds that "the spoken style lacks gravity, authority, dignity". In the mid-1960s, some Burmese writers spearheaded efforts to abandon

7810-410: The 19th century, in addition to concomitant economic and political instability in Upper Burma (e.g., increased tax burdens from the Burmese crown, British rice production incentives, etc.) also accelerated the migration of Burmese speakers from Upper Burma into Lower Burma. British rule in Burma eroded the strategic and economic importance of the Burmese language; Burmese was effectively subordinated to

The following are examples of varying vocabulary used for Buddhist clergy and for laity: Burmese primarily has a monosyllabic received Sino-Tibetan vocabulary. Nonetheless, many words, especially loanwords from Indo-European languages like English, are polysyllabic, and others, from Mon, an Austroasiatic language, are sesquisyllabic . Burmese loanwords are overwhelmingly in

8378-450: The Burmese language into Lower Burma also coincided with the emergence of Modern Burmese. As late as the mid-1700s, Mon , an Austroasiatic language, was the principal language of Lower Burma, employed by the Mon people who inhabited the region. Lower Burma's shift from Mon to Burmese was accelerated by the Burmese-speaking Konbaung Dynasty 's victory over the Mon-speaking Restored Hanthawaddy Kingdom in 1757. By 1830, an estimated 90% of

The earliest evidence of the Burmese alphabet is dated to 1035, while a casting made in the 18th century of an old stone inscription points to 984. Owing to the linguistic prestige of Old Pyu in the Pagan Kingdom era, Old Burmese borrowed a substantial corpus of vocabulary from Pali via

8804-488: The EAWM occurred 5.5 million years ago. The EAWM was still significantly weaker relative to today between 4.3 and 3.8 million years ago but abruptly became more intense around 3.8 million years ago as crustal stretching widened the Tsushima Strait and enabled greater inflow of the warm Tsushima Current into the Sea of Japan. Circa 3.0 million years ago, the EAWM became more stable, having previously been more variable and inconsistent, in addition to being enhanced further amidst

8946-516: The East Asian monsoon's strength began to wane, weakening from that point until the present day. A particularly notable weakening took place ~3,000 BP. The location of the EASM shifted multiple times over the course of the Holocene: first, it moved southward between 12,000 and 8,000 BP, followed by an expansion to the north between approximately 8,000 and 4,000 BP, and most recently retreated southward once more between 4,000 and 0 BP. The January ITCZ migrated further south to its present location during

A delay of a few days in the arrival of the monsoon can badly affect the economy, as evidenced in the numerous droughts in India in the 1990s. The monsoon is widely welcomed and appreciated by city-dwellers as well, for it provides relief from

9230-416: The Himalayan glaciers of Upper Burma near 28° N. The eastern branch of the two, N'mai, is the largest and rises in the Languela Glacier north of Putao . It is unnavigable because of the strong current whereas the smaller western branch, the Mali River, is navigable, despite a few rapids . Therefore, the Mali River is still called by the same name as the main river by locals. The controversial Myitsone Dam

9372-427: The Indian Ocean increased the intensity of monsoons. In 2018, a study of the SAM's variability over the past million years found that precipitation resulting from the monsoon was significantly reduced during glacial periods compared to interglacial periods like the present day. The Indian Summer Monsoon (ISM) underwent several intensifications during the warming following the Last Glacial Maximum, specifically during

Thus a better understanding of the possible links between El Niño , Western Pacific Warm Pool, Indonesian Throughflow, wind pattern off western Australia, and ice volume expansion and contraction can be obtained by studying the behaviour of the LC during Quaternary at close stratigraphic intervals. The South American summer monsoon (SASM) is known to have become weakened during Dansgaard–Oeschger events. The SASM has been suggested to have been enhanced during Heinrich events.

Regional differences between speakers from Upper Burma (e.g., Mandalay dialect), called anya tha ( အညာသား ) and speakers from Lower Burma (e.g., Yangon dialect), called auk tha ( အောက်သား ), largely occur in vocabulary choice, not in pronunciation. Minor lexical and pronunciation differences exist throughout the Irrawaddy River valley. For instance, for the term ဆွမ်း , "food offering [to

The weakening of the LC would have an effect on the sea surface temperature (SST) field in the Indian Ocean, as

10224-410: The Myitsone Dam construction will alter the hydrological characteristics of the river, e.g. preventing sediment from enriching riverbanks downstream, where it usually enriches the riverside food-producing plains. This can affect fertility as far downstream as the Irrawaddy Delta , the major rice-producing area of Myanmar. Ecological concerns focus on the inundation of an area that is the border of

10366-479: The OB vowel *u e.g. ငံ ngam 'salty', သုံး thóum ('three; use'), and ဆုံး sóum 'end'. It does not, however, apply to ⟨ည်⟩ which is never realised as a nasal, but rather as an open front vowel [iː] [eː] or [ɛː] . The final nasal is usually realised as nasalisation of the vowel. It may also allophonically appear as a homorganic nasal before stops. For example, in /mòʊɰ̃dáɪɰ̃/ ('storm'), which

10508-802: The South-East Asian region, with most going to China. Other countries targeted for power export are Thailand , India and Bangladesh . The largest of the seven, the Myitsone Dam , is located at the confluence of the Mali and N'Mai Rivers at the creation of the Irrawaddy. Although the China Power Investment Corporation is project manager of the Confluence Region Hydropower Projects. ParConfluence Region Hydropower Projects, several companies have been or are currently involved in

10650-667: The Southwest Monsoon first hits the Western Ghats of the coastal state of Kerala , India, thus making this area the first state in India to receive rain from the Southwest Monsoon. This branch of the monsoon moves northwards along the Western Ghats ( Konkan and Goa ) with precipitation on coastal areas, west of the Western Ghats. The eastern areas of the Western Ghats do not receive much rain from this monsoon as

10792-535: The Southwest Monsoon, receive rain from this Monsoon. About 50% to 60% of the rain received by the state of Tamil Nadu is from the Northeast Monsoon. In Southern Asia, the northeastern monsoons take place from October to December when the surface high-pressure system is strongest. The jet stream in this region splits into the southern subtropical jet and the polar jet. The subtropical flow directs northeasterly winds to blow across southern Asia, creating dry air streams which produce clear skies over India. Meanwhile,

10934-491: The adoption of neologisms. An example is the word "university", formerly ယူနီဗာစတီ [jùnìbàsətì] , from English university , now တက္ကသိုလ် [tɛʔkət̪ò] , a Pali-derived neologism recently created by the Burmese government and derived from the Pali spelling of Taxila ( တက္ကသီလ Takkasīla ), an ancient university town in modern-day Pakistan. Some words in Burmese may have many synonyms, each having certain usages, such as formal, literary, colloquial, and poetic. One example

11076-438: The air's ability to hold water , and this causes precipitation over the land. This is why summer monsoons cause so much rain over land. In the colder months, the cycle is reversed. Then the land cools faster than the oceans and the air over the land has higher pressure than air over the ocean. This causes the air over the land to flow to the ocean. When humid air rises over the ocean, it cools, and this causes precipitation over

11218-583: The arrival at the Eastern Himalayas, the winds turns towards the west, travelling over the Indo-Gangetic Plain at a rate of roughly 1–2 weeks per state, pouring rain all along its way. June 1 is regarded as the date of onset of the monsoon in India, as indicated by the arrival of the monsoon in the southernmost state of Kerala. The monsoon accounts for nearly 80% of the rainfall in India. Indian agriculture (which accounts for 25% of

11360-483: The average population density is 79 people/km. For these people, the river supply amounts to 18,614 m per person per year. Collectively, the modern Ayeyarwady (Irrawaddy) and Thanlwin (Salween) rivers deliver >600 Mt/yr of sediment to the sea. Most recent study shows: 1) There is little modern sediment accumulating on the shelf immediately off the Ayeyarwady River mouths. In contrast, a major mud wedge with

11502-507: The beginning of June, and again in mid- to late June. The European monsoon is not a monsoon in the traditional sense in that it doesn't meet all the requirements to be classified as such. Instead, the return of the westerlies is more regarded as a conveyor belt that delivers a series of low-pressure centres to Western Europe where they create unsettled weather. These storms generally feature significantly lower-than-average temperatures, fierce rain or hail, thunder, and strong winds. The return of

11644-662: The climax of summer heat in June. However, the roads take a battering every year. Often houses and streets are waterlogged and slums are flooded despite drainage systems. A lack of city infrastructure coupled with changing climate patterns causes severe economic loss including damage to property and loss of lives, as evidenced in the 2005 flooding in Mumbai that brought the city to a standstill. Bangladesh and certain regions of India like Assam and West Bengal , also frequently experience heavy floods during this season. Recently, areas in India that used to receive scanty rainfall throughout

11786-525: The close portions of the diphthongs are somewhat mid-centralized ( [ɪ, ʊ] ) in closed syllables, i.e. before /ɰ̃/ and /ʔ/ . Thus နှစ် /n̥iʔ/ ('two') is phonetically [n̥ɪʔ] and ကြောင် /tɕàũ/ ('cat') is phonetically [tɕàʊ̃] . Burmese is a tonal language , which means phonemic contrasts can be made on the basis of the tone of a vowel. In Burmese, these contrasts involve not only pitch , but also phonation , intensity (loudness), duration, and vowel quality. However, some linguists consider Burmese

11928-567: The coasts of the Rakhine State and Tanintharyi Region . On the Chindwin River , transportation is carried on by steam or diesel vessels throughout the year up to Homalin —about 640 km from its confluence with the Irrawaddy. Seasonal navigation is carried on into Tamanthi , which is 57 miles (92 km) by river above Homalin. The Chindwin valley has no railroad and relies heavily on river transport. Chauk , downstream from

12070-482: The confluence in the oil-field district, is a petroleum port. It is linked to Yangon by road and rail. Hinthada , near the apex of the delta, is the rail junction for lines leading to Kyangin and Bassein (Pathein). A ferry operates between Hinthada on the west bank and the railway station at Tharrawaw on the east bank. Myanmar's military junta signed an agreement with China Power Investment Corporation in May 2007 for

12212-600: The construction of seven hydroelectric dams along the Irrawaddy, Mali , and N'Mai River in Kachin State. The total planned output of all seven plants will be 15,160 MWs of electricity, making it the largest hydropower project in Myanmar, surpassing the 7100 MW Tasang Dam in Shan State. The following data is available for the dam locations: The power generated by the dams will be transmitted to other countries in

12354-460: The construction of seven hydroelectric dams , yielding a total of 13,360 MW, in the N'mai and Mali Rivers, including the 3600 MW Myitsone Dam at the confluence of both rivers. Environmental organisations have raised concerns about the project's ecological impact on the river's biodiverse ecosystems . Animals potentially impacted include the endangered Irrawaddy dolphin and the critically endangered Ganges shark . The name "Irrawaddy"

12496-412: The country with numbers as high as 10,000 animals, but in the last decade numbers have dwindled, partly due to transferring the animals to logging camps. Other species reported to be present include the leopard , Bengal tiger , crab-eating macaque , wild dog , and otters ( Panthera pardus, P. tigris, Cuon alpinus , and Lutra species). The saltwater crocodile ( Crocodylus porosus ) can be found in

12638-604: The country. These varieties include the Yaw , Palaw, Myeik (Merguese), Tavoyan and Intha dialects . Despite substantial vocabulary and pronunciation differences, there is mutual intelligibility among most Burmese dialects. Below is a summary of lexical similarity between major Burmese dialects: Dialects in Tanintharyi Region , including Palaw, Merguese, and Tavoyan, are especially conservative in comparison to Standard Burmese. The Tavoyan and Intha dialects have preserved

12780-451: The drier patches are the thorny Terminalia oliveri and the hardwood dahat teak ( Tectona hamiltoniana ) with stands of Indaing ( Dipterocarpus tuberculatus ) which is cut for timber. The wildlife includes many birds, small mammals and reptiles such as the huge Burmese python . However, most of the large animals including the tiger have been hunted out or seen their habitats disappear. The Irrawaddy River and its tributaries flow into

12922-516: The dry season. Between Myitkyina and Mandalay , the Irrawaddy flows through three well-marked defiles : This sheet of lava is the Singu Plateau , a volcanic field from the Holocene . This field consists of magma from the fissure vents and covers an area of about 62 square kilometres (24 sq mi). The plateau is also known as Letha Taung. Leaving this plateau at Kyaukmyaung ,

13064-669: The early post-independence era led to a reactionary switch from English to Burmese as the national medium of education, a process that was accelerated by the Burmese Way to Socialism . In August 1963, the socialist Union Revolutionary Government established the Literary and Translation Commission (the immediate precursor of the Myanmar Language Commission ) to standardize Burmese spelling, diction, composition, and terminology. The latest spelling authority, named

13206-401: The earth by conduction and not by convection. Therefore, bodies of water stay at a more even temperature, while land temperatures are more variable. During warmer months sunlight heats the surfaces of both land and oceans, but land temperatures rise more quickly. As the land's surface becomes warmer, the air above it expands and an area of low pressure develops. Meanwhile, the ocean remains at

13348-571: The easternmost stream is the Yangon River, on the left bank of which stands Myanmar's former capital city, Yangon (Rangoon). Because the Yangon River is only a minor channel, the flow of water is insufficient to prevent Yangon Harbour from silting up, and dredging is necessary. The relief of the delta's landscape is low but not flat. The soils consist of fine silt, which is replenished continuously by fertile alluvium carried downstream by

13490-416: The fish in the Irrawaddy river basin currently exists, but in 1996 it was estimated that there are about 200 species. In 2008, it was estimated that the Irrawaddy ecoregion is home to 119–195 species of fish found nowhere else in the world ( endemic ). Several new species of fish have been described from the Irrawaddy river basin in recent years (for example, the cyprinid Danio htamanthinus in 2016 and

13632-598: The form of nouns . Historically, Pali , the liturgical language of Theravada Buddhism , had a profound influence on Burmese vocabulary. Burmese has readily adopted words of Pali origin; this may be due to phonotactic similarities between the two languages, alongside the fact that the script used for Burmese can be used to reproduce Pali spellings with complete accuracy. Pali loanwords are often related to religion, government, arts, and science. Burmese loanwords from Pali primarily take four forms: Burmese has also adapted numerous words from Mon, traditionally spoken by

13774-508: The highest point is recorded in August, the lowest in February. This variation in water level makes it necessary for ports along the river to have separate landing ports for low- and high-water. Still, low water levels have caused problems for ports along the river, as in the Bamaw – Mandalay – Pyay sectors, the shallowest point is as shallow as 60 centimetres (2.0 ft). Within the basin ,

13916-459: The hot summers. This causes a low pressure area over the northern and central Indian subcontinent. To fill this void, the moisture-laden winds from the Indian Ocean rush into the subcontinent. These winds, rich in moisture, are drawn towards the Himalayas . The Himalayas act like a high wall, blocking the winds from passing into Central Asia, and forcing them to rise. As the clouds rise, their temperature drops, and precipitation occurs . Some areas of

14058-652: The interior of Asia as sea levels rose following the LGM; it also underwent a period of intensification during the Middle Holocene, around 6,000 years ago, due to orbital forcing made more intense by the fact that the Sahara at the time was much more vegetated and emitted less dust. This Middle Holocene interval of maximum EASM was associated with an expansion of temperate deciduous forest steppe and temperate mixed forest steppe in northern China. By around 5,000 to 4,500 BP,

14200-522: The introduction of English into matriculation examinations , fueled growing demand for Burmese to become the medium of education in British Burma; a short-lived but symbolic parallel system of "national schools" that taught in Burmese, was subsequently launched. The role and prominence of the Burmese language in public life and institutions was championed by Burmese nationalists, intertwined with their demands for greater autonomy and independence from

14342-491: The inundation include loss of farmland, loss of spawning habitat as fish can not swim upstream anymore. The Kachin Development Networking Group, a network of civil society groups and development organisations in Kachin State warn this will lead to a loss of income for fishermen. They report locals are also worried about the flooding of cultural sites in the flood zone. As with other large dam projects,

14484-526: The land area of Burma , and contains five of its largest cities. As early as the sixth century, the river was used for trade and transport, and an extensive network of irrigation canals was developed to support agriculture. The river is still of great importance as the largest commercial waterway of Myanmar. It also provides important ecosystem services to different communities and economic sectors, including agriculture, fisheries, and tourism. In 2007, Myanmar's military dictatorship signed an agreement for

14626-515: The literary form, asserting that the spoken vernacular form ought to be used. Some Burmese linguists such as Minn Latt , a Czech academic, proposed moving away from the high form of Burmese altogether. Although the literary form is heavily used in written and official contexts (literary and scholarly works, radio news broadcasts, and novels), the recent trend has been to accommodate the spoken form in informal written contexts. Nowadays, television news broadcasts, comics, and commercial publications use

14768-618: The maximum approximately 80 years, similar to today. A study of marine plankton suggested that the South Asian Monsoon (SAM) strengthened around 5 million years ago. Then, during ice periods, the sea level fell and the Indonesian Seaway closed. When this happened, cold waters in the Pacific were impeded from flowing into the Indian Ocean. It is believed that the resulting increase in sea surface temperatures in

14910-610: The monsoon in South Asia is influenced by the high Tibetan Plateau. These temperature imbalances happen because oceans and land absorb heat in different ways. Over oceans, the air temperature remains relatively stable for two reasons: water has a relatively high heat capacity (3.9 to 4.2 J g K ), and because both conduction and convection will equilibrate a hot or cold surface with deeper water (up to 50 metres). In contrast, dirt, sand, and rocks have lower heat capacities (0.19 to 0.35 J g K ), and they can only transmit heat into

15052-513: The monsoon is not a simple response to heating but a more complex interaction of topography, wind and sea, as demonstrated by its abrupt rather than gradual withdrawal from the region. The Australian monsoon (the "Wet") occurs in the southern summer when the monsoon trough develops over Northern Australia . Over three-quarters of annual rainfall in Northern Australia falls during this time. The European Monsoon (more commonly known as

15194-399: The mud deposit is up to 20 m nearshore and gradually thins to the slope at −300 m water depth, and likely escapes into the deep Andaman Trench; 4) The estimated total amount of Holocene sediments deposited offshore is ~1290 × 10 tons. If we assume this has mainly accumulated since the middle Holocene highstand (~6000 yr BP) like other major deltas, the historical annual mean depositional flux on

15336-453: The northern tip of Myanmar – the Kachin State – they cut long north–south alluvial plains and relatively narrow upland valleys between the 2,000 to 3,000 metres (7,000–10,000 ft) mountain ridges. The rivers joining the Irrawaddy are, from north to south: As early as the sixth century, the Bamars were using the Irrawaddy to gain power in the region through trade and transport on

15478-530: The north–south course of the Irrawaddy River, a number of notably different ecoregions can be distinguished. The streams of the Nmai and Mali that form the Irrawaddy originate in high and remote mountains near the border with Tibet . This part of Myanmar, which extends north from Myitkyina and the Irrawaddy confluence, lies entirely outside the tropics. Rain falls at all seasons of the year, but mostly in

15620-408: The oceans. (The cool air then flows towards the land to complete the cycle.) Most summer monsoons have a dominant westerly component and a strong tendency to ascend and produce copious amounts of rain (because of the condensation of water vapor in the rising air). The intensity and duration, however, are not uniform from year to year. Winter monsoons, by contrast, have a dominant easterly component and

15762-466: The only way across the Irrawaddy was by ferry. The bridge was destroyed by the retreating British Army during World War II and was rebuilt in 1954 after Burmese independence and was the only bridge to span the Irrawaddy until recent times when a spate of bridge construction has been carried out by the government. Burmese language Burmese is a tonal , pitch-register , and syllable-timed language , largely monosyllabic and agglutinative with

15904-585: The population in Lower Burma self-identified as Burmese-speaking Bamars; huge swaths of former Mon-speaking territory, from the Irrawaddy Delta to upriver in the north, spanning Bassein (now Pathein) and Rangoon (now Yangon) to Tharrawaddy, Toungoo, Prome (now Pyay), and Henzada (now Hinthada), were now Burmese-speaking. The language shift has been ascribed to a combination of population displacement, intermarriage, and voluntary changes in self-identification among increasingly Mon–Burmese bilingual populations in

16046-550: The preparation, construction and financing of the 3,600 MW Myitsone Dam. Asia World Company has a key position, amidst Burmese Suntac Technologies and state-run Myanmar Electrical Power Enterprise, a state-owned utility enterprise responsible for power generation, transmission and distribution Chinese involvement comes from China Power Investment Corporation , China Southern Power Grid , Yunnan Machinery Equipment Import & Export Company Changjiang Institute of Surveying, Planning, Design and Research. At least one Japanese company

16188-649: The region, such as the 5.3 magnitude earthquake that struck near the Myanmar-China border on 20 August 2008, prompted Naw Lar, the coordinator of the KDNG dam research project, to ask the junta to reconsider its dam projects. The river flows through or past the following cities: Until the construction of the Ava (Innwa) Bridge, a 16 span rail and road cantilever bridge built by the British colonial government in 1934,

16330-425: The region. Standardized tone marking in written Burmese was not achieved until the 18th century. From the 19th century onward, orthographers created spellers to reform Burmese spelling, because of ambiguities that arose over transcribing sounds that had been merged. British rule saw continued efforts to standardize Burmese spelling through dictionaries and spellers. Britain's gradual annexation of Burma throughout

16472-510: The region. Examples are the formation of a rare low-latitude tropical storm in 2001, Tropical Storm Vamei , and the devastating flood of Jakarta in 2007. The onset of the monsoon over Australia tends to follow the heating maxima down Vietnam and the Malay Peninsula (September), to Sumatra , Borneo and the Philippines (October), to Java , Sulawesi (November), Irian Jaya and northern Australia (December, January). However,

16614-455: The river follows a broad, open course through the central Dry Zone – the Bamar people's ancient cultural heartland – where large areas consist of alluvial flats. From Mandalay (the former capital of the kingdom of Myanmar), the river makes an abrupt westward turn before curving southwest to unite with the Chindwin River , after which it continues in a southwestern direction. It is probable that

16756-419: The river. As a result of heavy rainfall varying from 2,000 to 3,000 millimetres (79–118 in) a year in the delta, and the motion and sediment load of the river, the delta surface extends into the Andaman Sea at a rate of about 50 metres (160 ft) per year. Due to monsoonal rains, which occur between mid-May and mid-October, the volume of the Irrawaddy and its tributaries varies greatly throughout

16898-510: The said pronoun is used only by male speakers while ကျွန်မ , kya.ma. [tɕəma̰] is used by female speakers. Moreover, with regard to kinship terminology , Upper Burmese speakers differentiate the maternal and paternal sides of a family, whereas Lower Burmese speakers do not. The Mon language has also influenced subtle grammatical differences between the varieties of Burmese spoken in Lower and Upper Burma. In Lower Burmese varieties,

17040-523: The shelf would be 215 Mt/yr, which is equivalent to ~35% of the modern Ayeyarwady-Thanlwin rivers derived sediments; 5) Unlike other large river systems in Asia, such as the Yangtze and Mekong, this study indicates a bi-directional transport and depositional pattern controlled by the local currents that are influenced by tides, and seasonally varying monsoons winds and waves. No complete and precise list of all

17182-412: The southern part of the delta. The species was formerly abundant in coastal regions, but population numbers have decreased because of a combination of commercial skin hunting, habitat loss, drowning in fishing nets and over-collection of living animals to supply crocodile farms . It was at this river that a battle between a saltwater crocodile and a tiger was observed that ended with the reptile devouring

17324-666: The southwest bringing heavy rainfall to the area. The etymology of the word monsoon is not wholly certain. The English monsoon came from Portuguese monção ultimately from Arabic موسم ( mawsim , "season"), "perhaps partly via early modern Dutch monson ". Strengthening of the Asian monsoon has been linked to the uplift of the Tibetan Plateau after the collision of the Indian subcontinent and Asia around 50 million years ago. Because of studies of records from

17466-471: The species is now extinct in Myanmar. Several species of large mammal occur in the delta, but their populations are small and scattered, with the possible exceptions of the Malayan sambar deer ( Cervus unicolor equinus ), Indian hog deer ( C. porcinus ), and wild boar ( Sus scrofa ), which have been reported from all Reserved Forests. Asian elephants ( Elephas maximus ) were once widespread throughout

17608-764: The spoken form or a combination of the spoken and simpler, less ornate formal forms. The following sample sentence reveals that differences between literary and spoken Burmese mostly occur in affixes: Burmese has politeness levels and honorifics that take the speaker's status and age in relation to the audience into account. The suffix ပါ pa is frequently used after a verb to express politeness. Moreover, Burmese pronouns relay varying degrees of deference or respect. In many instances, polite speech (e.g., addressing teachers, officials, or elders) employs feudal-era third person pronouns or kinship terms in lieu of first- and second-person pronouns. Furthermore, with regard to vocabulary choice, spoken Burmese clearly distinguishes

17750-562: The subcontinent receive up to 10,000 mm (390 in) of rain annually. The southwest monsoon is generally expected to begin around the beginning of June and fade away by the end of September. The moisture-laden winds on reaching the southernmost point of the Indian Peninsula , due to its topography, become divided into two parts: the Arabian Sea Branch and the Bay of Bengal Branch . The Arabian Sea Branch of

17892-493: The summer monsoon shifts through a series of dry and rainy phases as the rain belt moves northward, beginning over Indochina and the South China Sea (May), to the Yangtze River Basin and Japan (June) and finally to northern China and Korea (July). When the monsoon ends in August, the rain belt moves back to southern China. The rainy season occurs from September to February and it is a major source of energy for

18034-683: The summer. The valleys and lower hill ranges are covered with tropical and subtropical evergreen rainforest instead of monsoon (deciduous) forest. This region is characterised by subtropical and temperate forests of oak and pine are found at elevations above 900 metres (3,000 ft). This evergreen forest passes into sub-tropical pine forest at about 1,500 metres (4,900 ft) feet. Above 1,800 metres (5,900 ft), are forests of rhododendrons , and that in turn into evergreen conifer forest above 2,400 metres (7,900 ft) feet. The Irrawaddy river basin covers an approximate area of 255 81 km (31 sq mi). The Central Basin consists of

18176-520: The tiger. Despite recent declines in the sea turtle populations, five species are known to nest in Myanmar at well known island and mainland beaches known as turtle-banks. These are the olive ridley sea turtle ( Lepidochelys olivacea ), the loggerhead sea turtle ( Caretta caretta ), the green sea turtle ( Chelonia mydas ), the hawksbill sea turtle ( Eretmochelys imbricata ), and the leatherback sea turtle ( Dermochelys coriacea ). The Irrawaddy River has five major tributaries. As they flow through

18318-633: The time intervals corresponding to 16,100–14,600 BP, 13,600–13,000 BP, and 12,400–10,400 BP as indicated by vegetation changes in the Tibetan Plateau displaying increases in humidity brought by an intensifying ISM. Though the ISM was relatively weak for much of the Late Holocene, significant glacial accumulation in the Himalayas still occurred due to cold temperatures brought by westerlies from

18460-448: The traditional homeland of Burmese speakers. The 1891 Census of India , conducted five years after the annexation of the entire Konbaung Kingdom , found that the former kingdom had an "unusually high male literacy" rate of 62.5% for Upper Burmans aged 25 and above. For all of British Burma , the literacy rate was 49% for men and 5.5% for women (by contrast, British India more broadly had a male literacy rate of 8.44%). The expansion of

18602-425: The underlying orthography . From the 1500s onward, Burmese kingdoms saw substantial gains in the populace's literacy rate , which manifested itself in greater participation of laymen in scribing and composing legal and historical documents, domains that were traditionally the domain of Buddhist monks, and drove the ensuing proliferation of Burmese literature , both in terms of genres and works. During this period,

18744-549: The upper Irrawaddy originally flowed south from Mandalay, discharging its water through the present Sittaung River to the Gulf of Martaban , and that its present westward course is geologically recent. Below its confluence with the Chindwin, the Irrawaddy continues to meander through the petroleum producing city of Yenangyaung , below which it flows generally southward. In its lower course, between Minbu and Pyay , it flows through

18886-504: The valley of the middle Irrawaddy and lower Chindwin. It lies within the 'dry zone' and consists almost entirely of plains covered with the teak -dominated Irrawaddy moist deciduous forests ecoregion , which surrounds dry forest patches in drier areas. The central basin receives little rain (ave 650mm per year) although it does flood quickly during the July–October storms. The one meteorological factor which does not vary greatly, and which

19028-462: The verb ပေး ('to give') is colloquially used as a permissive causative marker, like in other Southeast Asian languages, but unlike in other Tibeto-Burman languages. This usage is hardly used in Upper Burmese varieties, and is considered a sub-standard construct. More distinctive non-standard varieties emerge as one moves farther away from the Irrawaddy River valley toward peripheral areas of

19170-794: The west. During the Middle Miocene , the July ITCZ, the zone of rainfall maximum, migrated northwards, increasing precipitation over southern China during the East Asian Summer Monsoon (EASM) while making Indochina drier. During the Late Miocene Global Cooling (LMCG), from 7.9 to 5.8 million years ago, the East Asian Winter Monsoon (EAWM) became stronger as the subarctic front shifted southwards. An abrupt intensification of

19312-466: The wide circulation of legal texts, royal chronicles , and religious texts. A major reason for the uniformity of the Burmese language was the near-universal presence of Buddhist monasteries (called kyaung ) in Burmese villages. These kyaung served as the foundation of the pre-colonial monastic education system, which fostered uniformity of the language throughout the Upper Irrawaddy valley,

19454-656: The wind does not cross the Western Ghats. The Bay of Bengal Branch of Southwest Monsoon flows over the Bay of Bengal heading towards north-east India and Bengal , picking up more moisture from the Bay of Bengal. The winds arrive at the Eastern Himalayas with large amounts of rain. Mawsynram , situated on the southern slopes of the Khasi Hills in Meghalaya , India, is one of the wettest places on Earth. After

19596-410: The word "television", Burmese publications are mandated to use the term ရုပ်မြင်သံကြား (lit. 'see picture, hear sound') in lieu of တယ်လီဗီးရှင်း , a direct English transliteration. Another example is the word "vehicle", which is officially ယာဉ် [jɪ̃̀] (derived from Pali) but ကား [ká] (from English car ) in spoken Burmese. Some previously common English loanwords have fallen out of use with

19738-477: The year, but from Bhamo to Myitkyina (200 km) for only seven months. More than 3,200 kilometres (2,000 mi) of navigable waterways exist in the Irrawaddy delta, and there is a system of connecting canals. The Sittang is usable by smaller boats, but the Salween River , because of its rapids, is navigable for less than 160 kilometres (99 mi) from the sea. Small steamers and country boats also serve

19880-536: The year, like the Thar Desert , have surprisingly ended up receiving floods due to the prolonged monsoon season. The influence of the Southwest Monsoon is felt as far north as in China's Xinjiang . It is estimated that about 70% of all precipitation in the central part of the Tian Shan Mountains falls during the three summer months, when the region is under the monsoon influence; about 70% of that

20022-544: The year. In summer, the melting of the snow and glaciers in Northern Burma add to the volume. The average discharge near the head of the delta is between a high of 32,600 cubic metres (1,150,000 cu ft) and a low of 2,300 cubic metres (81,000 cu ft) per second. The discharge can be as high as 40,393 cubic meter per second in the rainy season. Over a year, the discharge averages 15,112 cubic metres (533,700 cu ft). Further North, at Sagaing ,

20164-777: Was the fifth of the Sino-Tibetan languages to develop a writing system, after Classical Chinese , Pyu , Old Tibetan and Tangut . The majority of Burmese speakers, who live throughout the Irrawaddy River Valley, use a number of largely similar dialects, while a minority speak non-standard dialects found in the peripheral areas of the country. These dialects include: Arakanese in Rakhine State and Marma in Bangladesh are also sometimes considered dialects of Burmese and sometimes as separate languages. Despite vocabulary and pronunciation differences, there
